Dear Conveyor Belt User,
The ConveyorBeltGuide is providing practical information about heavy duty conveyor belts, which normally is not found on commercial websites. It is permanently growing and improving. You are kindly invited to send your comments or questions.
With your support this guide will become better and better for the benefit of all who are working with this great product.
We suggest that you start navigating with BELTEDIA or you go to First Aid in case of issues with your belt.

Six miners killed in a conveyor belt disaster
South Africa's Minister of Mineral Resources, Gwede Mantashe, said on 2018-07-18: “We reiterate our call to mining companies to prioritise the safety of employees at all times. The department of mineral resources will proceed with an investigation into the cause of the accident at Palabora Mining Company, soon after the fire underground has been extinguished and the area is declared safe.”
The CIM Magazine (Canadian Institute of Mining) has published an interesting article named Unnecessary interruptions about improved material handling through smarter modelling, design and monitoring.

Vale inaugurated world's largest truckless mine
On 2016.12.17, Vale inaugurated world's largest mining project ever, with a production of 90 Mt/a of iron ore to be reached in 2020. S11D is a truckless mine with a total belt conveyor length of 68 km. The system replaces traditional mining trucks (OHT); 100 of them with a capacity of 240 t would have been required. Without trucks, Vale reduces fuel consumption by 80 %, and significantly reduces waste such as tires, filters and lubricants. There will be at least 50 % of greenhouse gas emissions (= 130.000 t of CO2) less per year. And 18.000 MWh/a of electricity are going to be saved.

Smart conveyor belt design
A smart way to design conveyor belts as per DIN 22101 (2002 or 2011 issues) employing dynamic splice efficiency, is reducing the belt rating and bringing down overall costs. It is described in a paper called "State-of-the-art long distance conveyor belt design" published in Coal Asia Magazine.
